Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of motor slip ring parts, and particularly relates to a slip ring structure. Background Art
[0002] The slip ring in a motor is an annular part mainly used for conducting current. It is usually installed on the rotor shaft of the motor and is in close contact with the carbon brush, playing the role of transmitting current. Through its conductivity, the slip ring enables the current to be smoothly transmitted to the rotor, thereby driving the motor to operate. The slip ring is applied in various fields and is used to connect with a rotating body to transmit electrical signals. In particular, it is one of the indispensable components in a motor.
[0003] The problems existing in the prior art are as follows: In the production of traditional slip ring parts, a ring-shaped thin sheet structure is formed by stamping to protect the ring-shaped main body part, and a plurality of conductive contacts in contact with the carbon brush are arranged on the main body part.
[0004] Under the stamping process, the conductive contact is a part bent out from the ring-shaped main body part and is integral with the ring-shaped main body. Since the conductive contact needs to always contact the carbon brush, and the rotation of the carbon brush will continuously squeeze the conductive contact, causing the conductive contact to bend towards the side away from the carbon brush. In order for the conductive contact to have good conductivity, the traditional solution is to use copper or copper alloy to manufacture the slip ring. Although the conductivity is beneficial, the materials of copper and copper alloy themselves have insufficient toughness. During long-term use, they are continuously squeezed by the carbon brush, and finally, they are bent too much to recover, disconnecting the contact with the carbon brush, resulting in the failure of the slip ring. The use of copper or copper alloy for stamping the entire slip ring also makes the manufacturing cost too high.
[0005] Moreover, the traditional integrally stamped conductive contact cannot be replaced separately after long-term contact wear with the carbon brush, and the entire slip ring must be replaced, which also increases the maintenance cost. Summary of the Utility Model
[0006] The utility model provides a slip ring structure to solve the above technical deficiencies.
[0007] The technical solution of the utility model: A slip ring structure includes an annular main body and a plurality of conductive contacts. A plurality of connecting platform parts are arranged on one side of the relatively inner ring of the annular main body. The conductive contact has an L-shaped structure and includes a base part detachably and fixedly connected to the connecting platform part and a conductive part in contact with the carbon brush. The conductive part extends axially, and a convex contact head is arranged on the end face of the side close to the center of the circle. The conductive contact is made of spring steel material.
[0008] Adopting the above technical solution, by separately setting the slip ring into an annular main body and several conductive contacts, and using the detachable structure of the conductive contacts for assembly, when a certain conductive contact is worn, only one conductive contact needs to be replaced and then assembled, so that it can be repaired and reused, reducing the part maintenance cost. Utilizing the high toughness of spring steel to overcome the problem that the conductive contact is difficult to recover due to the deformation caused by the brush contact, so as to keep the conductive contact always in contact with the brush.
[0009] A further setting of the present utility model: at corresponding positions of the connecting table part and the base part, there are a first riveting hole and a second riveting hole, and the base part and the connecting table part are connected by a rivet, and the rivet is made of copper or copper alloy material.
[0010] Adopting the above technical solution, through the riveting form for assembly, and at the same time the rivet is made of copper or copper alloy material, improving the electrical conductivity at the connection between the conductive contact and the annular main body.
[0011] A further setting of the present utility model: the connecting table part is provided with two first riveting holes, and two conductive contacts are arranged on each connecting table part.
[0012] Adopting the above technical solution, two conductive contacts are arranged on one connecting table part to contact the brush. Even if one conductive contact fails, there is another set as a safety measure, improving the stability of the slip ring.
[0013] A further setting of the present utility model: the annular main body is made of carbon steel material, the cross section of the annular main body is in an L shape, and several weight reduction notches are arranged around the inner circle, and three connecting table parts are equally divided on the annular main body.
[0014] Adopting the above technical solution, after separate setting, it is not necessary for the annular main body to adopt copper or copper alloy material with higher cost. As the main body frame, carbon steel that meets the strength requirements can be used. At the same time, weight reduction notches are set to reduce the overall weight of the slip ring.
[0015] A further setting of the present utility model: the thickness of the annular main body is 0.6 - 0.8 mm, and the thickness of the conductive contact is 0.2 mm.
[0016] The beneficial effects of the present utility model: by separately setting the slip ring into an annular main body and several conductive contacts, and using the detachable structure of the conductive contacts for assembly, when a certain conductive contact is worn, only one conductive contact needs to be replaced and then assembled, so that it can be repaired and reused, reducing the part maintenance cost. Utilizing the high toughness of spring steel to overcome the problem that the conductive contact is difficult to recover due to the deformation caused by the brush contact, so as to keep the conductive contact always in contact with the brush. And two conductive contacts are arranged on one connecting table part to contact the brush, improving the stability of the slip ring. Description of the Drawings
